- Heat the oil in a large pot over medium low heat. Add the onion and sauté until softened and translucent, about 8-10 minutes. Add the garlic and cook an additional 30 seconds.

- Add the crushed tomatoes, basil, tomato paste, sugar, salt, and pepper, to taste. Stir to combine and simmer uncovered over low heat for 20-30 minutes. The longer the sauce simmers, the more flavorful it will be.
